Coach Patterson on Justin Sinz…
"I'm just big on chemistry and when you have connections and ties to people and you've worked with people, you know what you're getting. In my conversations with Justin it was very apparent he comes from a coaching family much like myself. He is a great fit for ACU. Sometimes conversations tend to be a little bit forced, but it was very easy talking with Justin about what we're trying to do here."
